Fuel efficiency switch |
3 Mode |
M Booster+ |
Tata & Eicher drivers are able to tune engines with FE switch depending upon load and gradient conditions for higher KMPL |
||
Gear shift indicator |
This feature is very much required in BS6 as the driving parameters have changed. Drivers are able to achieve higher KMPL if they follow the advise |
||||
BS6 Norms |
Pure SCR (Flex Module) |
EGR + SCR (Switch back) |
EGR + SCR (Switch back) |
EGR + SCR (C type) |
Pure SCR is a globally proven mechanism in bigger engines. EGR+SCR combination reduces AdBlue consumption |
| Clutch | 430mm Organic | 395mm Ceramic | 380mm Ceramic | 430mm Organic | Tata & Eicher are offering bigger 430 mm dia clutch for better power transmission & longer life |
| Gear Box | G1150-9S | ZF9S1110 | ZF9S1110 | ET140S9 | All the OEMs are offering 9 speed gear box as the tonnage to be carried is on higher side |
